Sharknado may not have been a ratings smash, but it got to be a social media phenomenon thanks to its bizarre premise and tongue-in-cheek marketing campaign. Now Syfy’s big challenge will be to top themselves, and the first of their films to try will be the kinda-sorta-not-really similarly themed Ghost Shark.

As with Sharknado, the title is entirely self-explanatory. Taking the Ian Ziering / Tara Reid slot of fondly remembered ’90s star this time around is Mackenzie Rosman, best remembered as little Ruthie Camden from 7th Heaven. Yes, that’s her in the bikini above, and yes, it’s super weird to see her all grown up. Check out the first trailer after the jump.
